【摘要】 在００２５ｍｏｌ／ＬＨ２ＳＯ４介质中及紫外光辐照条件下，吲哚乙酸发生光异构化反应，生成一种玫瑰色产物．采用紫外＿可见分光光度、红外光谱、高效液相色谱、荧光法等手段研究和论证了吲哚乙酸的光异构化反应．建立了一个检出限和测定范围分别为０１ｍｇ／Ｌ和０３～３０ｍｇ／Ｌ吲哚乙酸的光化学反应新方法，并用于农药样品分析更多还原

【Abstract】 Under UV_light irradiation, indolylacetic acid in a 0.025 mol/L H 2SO 4 solution activates photoisomerization reaction and forms a rose indolylvinyl acid. The reaction has been investigated by UV_spectrophotometry(using 485 nm), spectrofluorimetry, IR and HPLC. A novel photochemical analytical method for determining the 0.3～30 mg/L indloylacetic acid has been described and applied to analysize indolylacetic acid in pesticide samples.更多还原
